Household Ingredient Gnat Trap

Here’s an homemade trap built around an old plastic bottle. Wash the bottle and cut off the top. Mark the center of the bottle with a permanent marker. This will serve as a “fill to” line. Dissolve 3 tablespoons of sugar in 1/4 cup of vinegar and pour it into the bottle. Add water up to the fill line. Place the cutoff top upside down in the bottle. The gnats can easily get into the wide opening, but it’s difficult for them to get back out. Place this on your kitchen counter or any area where you’ve seen a lot of gnats congregating.

Simple Three-Step Gnat Trap

Attracted by wet soil, gnats love houseplants. To get rid of them, spread a little honey on bright yellow index cards. Glue the card to a straw or chopstick and stick into the soil of the gnat’s favorite houseplants. Yellow attracts gnats because it’s the color of plants under stress whose defenses are weakened against predators. When the gnats come to investigate, they’ll get stuck in the honey.

Red Wine Gnat Trap

Make a homemade gnat trap with a shallow dish and red wine, which will attract gnats. Some people use a container with a small opening, like a water bottle, so it’s more difficult for the gnats to fly away after they investigate the wine. These traps also work on fruit flies, which are not the same as gnats.
